SPECIPCATON forming part of Letters Patent No. 323,475, dated August 4, 1885.

Appnmnnn nien 'Maren 21, niet. (No model To a/ZZ whom, t may concern:

Beit known that I, ELMER L. NVILLIAMs, a citizen of the United States, residing at Buchanan, in the county of Berrien and State ot' Michigan, have invented certain new and useful Improvements in Glover- Hullers, of which the following is a specification.

The objects of my improvements are to provide a clover-holler which will do the hulling and separat-ing more thoroughly than the hullers now in use, which will save all the seed, and one in which the hulling cylinder and concave can be taken out and repaired with ont disturbing any other parts of the machine. l obtain these objects by the mechanism illus trated in the accompanying drawings, in which- Figure l is a side view of the machine; Fig. 2, a longitudinal vertical section through the same; Fig. 3, a vertical crosssection on line :c a' on Figs. l and 2; Fig. 4, a longitudinal vertical section through the hulling cylinder and concave; Fig. 5, a vertical cross-section through the hulling cylinder and concave, showing also part of the cylinder and of the concave in elevation; Fig. 6, a detail View of the lugs or projecting rubber sections, which, bolted in place in continuous rows, form the inside of the helling-concave; Fig. 7, a detail view of the teeth on the periphery of the helling-cylinder; Fig. 8, a large scale longitudinal vertical section through the hullingcylinder and adjoining parts; Fig. 9, a large scale vertical cross-section through the hulling-cylinder and adjoining parts; Fig. 10, a large scale longitudinal vertical section through the tailing-box and the end of the cleaningshoe,with the removable stenrcut-off bar.

Similar letters referto similar' parts through out the several views.

The sides of the rubber sections h hare shown corrugated on only a few of the studs in Figs. 2 and 4, so as not to obscure the drawings. For the saine reason not all theL cylindersections are section-lined on Fig. 3.

A is the frame-work of the machine, mounted on the running-gear S S, and forming the chamber B, in which the thrashing, hnllinv, and separating are done.

C is the tlirashingcylinder; D, the rakes or separating device. Said separating device is constructed in the usual manner, with longitudinal bars d cl3, between which the rakerbars d d, that are provided at the top with the fingers d d and at the bottom with the forks d2 d2, operate, the bars d d being connected to a crankshaft, by which they receive the forward and backward motion. E is a solid bottoni extending across the chamber B. The

- rakecbars d d, being mounted on and operated by a crank-shaft, move the straw over the bars cl3 di toward the rear of the machine, discharging it there, while the seed, chaff, Src., being shaken and separated from the straw by the lifting and shifting movement of the iingers d d', drop through between the raker-bars d d and the bars d* di' onto the door E, from where they are removed by the forks d,Z (Z2 toward the front and to the hulling-cylinder G.

F is a screen-slide, which extends across the chamber B, and can be drawn out when de sired. O is ashaking door, oscillated in the usual manner, slanting from under the thrashing concave and cylinder C back to the mouth of the hulling-cylinder G, and conveying any seed separated from the straw by the thrashing-cylinder G and the fore end of the rake D to said boiling-cylinder G.

R is a distributing screw-conveyer. The tailings, die., that are elevated from the tailingbox j by the elevator L into this conveyer It are by its screw distributed across the width of the machine and emptied into the hulling- 'oylinder G. By placing the distributing conveyer It back of and close to the hulling-cylinde-r G, and thus emptying the tailings directly into the hulling-cylinder G, l obtain better results than where the tailings are emptied into the thrashingcylindcr or onto the separatingrakes, in which case the straw becomes more or less clogged and burdened, so that a certain amount of seed will not be separated from the same, but be carried out with it at the rear.

is a solid bottom underthe screw-conveyor B, slant-ing towards the hullingcylinder and forming a front continuation of the floor E and the screen-slide F.

The hulling cylinder and concave G are all located below and back of the thrashingeylinder C, and constructed in the following man- IOO ner: To the cylinder-shaft gis keyed at one end the cylinder-head g. Then a cylindersection, g2, provided with the teeth t t t on its periphery, is slipped over the shaft g close up to the cylinder-head g and firmly secured in place on the shaft. Then a cylinder-section, g3, with corrugated periphery, is slipped over the shaft r/ tight up to the section g2, and secured to the shaft g; then another section, gl and g3, and so on, until the hulling-cylinder is completed by another head-piece g.

The concave H, which is madein two halves erosswise, is lined on the inside with the arcshaped projecting rubber sections orlugs h L, which are bolted to the concave H by the bolts h2 h2.V `The rubber sections h h have corrugated sides and a corrugated surface toward the hulling-cylinder,provided with a hole, h', for the bolt h2 to pass through, the sides of the rubber sections slanting out toward the concave H. rIhe rubber sections hh, being bolted to the concave I-I in continuons parallel rows spaced at equal distances apart laterally, form vV-shaped grooves, through which the teeth t t t of the cylinder-sections g2 pass. The teeth t t, being either firmly secured to or forming part ofthe sections g2, have corrugated sides and top surface and a smooth beveled front edge or lead or forward portion. This smooth beveled lead or forward portion, While taking hold of the chaff, weeds, stems, and seed,grad ually lattens the same out in the corrugated grooves Without causing any clogging or cracking of the seed, and no seed will be pushed ahead of the teeth out of the concave without beinghulled. Theteeth areintheshape ofaninvertedV,beingthickerattheirbasethan at t-hctop, corresponding to the grooves formed by the sides of the rubber sections h 7L, in which grooves the teeth tt operate. By having the teeth thicker at their base more strength is given to them, and the liability of their breaking off of the cylinder lessened.

The cylinder-sections g3 g may either have thin corrugated surface-plates secured to their periphery, or the surface of the sections may .be cast or worked corrugated.

The corrugated teeth i t, operating and fitting closely in the corrugated grooves formed by the rubber sections lr 7L 71, and the corrugated surface of the cylinder-sections g g3 coming close to the corrugated surface of the concave rubber sections l1 Il, a very large rubbing surface and a device is obtained in which the hulling is done most eHectively, so that none or only very few seeds will leave the concave unhulled. The concave being constructed in the described manner can easily be repaired. There being no large sections of lining, but only the small rubber sections 71` 71damaged or broken studs can be taken out and replaced with little trouble and expense. The cylinder, being formed in sections slipped over and secured to the shaft g, can also easily be repaired, broken sections can be replaced,

and,another great advantage, the cylinder can perfectly be balanced. Y

The entire hulling concave and cylinder are secured to a frame, P, whichframe rests upon cross-beams of the frame A, and is secured in position, by bolts and nuts or other suitable means, and can be drawn out of the chamber B laterally When the concave or cylinder needs repairs. Then in place the frame P is secured to the machine-frame A by butts or any other suitable devices. By having the hulling concave and cylinder thus made removable I am enabled to make repairs to them without disturbing any other parts of the machine, whieh insures a great saving of time and labor.

The removable-screen-slide R is located right back of the distributing screw-conveyer R. Its office is to allow theV seed whichl has already been hulled by having undergone the thrashing and shaking process .to drop onto the cleaning shoe and riddle I Without passing through the hulling-cylinder G, thus lessening the work of the cylinder and preventing any clogging and cracking of the seed. It also enables me to use the machine for thrashing timothy, the seeds dropping through said screen F onto the riddle I. Vhen the screen F should become clogged with dirt, chaff, or seed it can be drawn out and cleaned.

I is the cleaning-shoe,oscillated in the usual manner, z' being the riddle, t" the sieve, and :i2 the screen, slanting forward to the seedchute N.

k are the pitman-rods and lever, which, being connectedwith an eccentric v on the fanshaft K, or any other shaft, oscillate the shoe I.

The improvement I make in the cleaningshoe I is as follows: I extend the screen-Hoor 2 of the shoe I beyond the ends of the riddle and sievez' and i', and there secure to said floor a removable eut-off bar, p, extending over and across the entire iioor i2. If this bar pis placed back of the ends ofthe riddle and sieve i and t', the stems or heavier substances that are not entirely blown out of the chamber B by the blast of the fan K drop from the ends of the said riddle and sievez' and 'i' onto the screen-Hoor i2, are prevented from going over the end of said screen-floor i2 into the 'railing-box j by the aforesaid cut-off bar p, and slide down on the screen t', emptyinginto the stem-chute M. If it is desired to have the stems and heavier substances undergov the hulling and cleaning process a second time, on account of the seed that may yet be contained in the same, I change the location of the cutoff bar p so that it is under the ends of the riddle and Vscreen i and i', as shown by dotted lines on Figs. 2 and l0. The stems will then drop into the tailingsboX j, will be elevated from there by the commoni'elevator, L, and be emptied into `the distributing -conveyer B, which, extending across the chamber B, conveys the same to the hulling-cylinder G. The

IOO

IIO

cut-od' bar p is secured in-either position to l the screen-door i? by nails, screws, clamps, or other suitable means which will admit of changing the location of the bar without much trouble or loss of time.

N is the chute into which the clean seed collect that have passed through the cleaning-shoe I onto the ioor J. The stem-chute M is constructed in the following manner: A solid slanting bottom, m', extends across the entire Width of the machine, While a little above the same is located a perforated false bottom, m, running out some distance over one end at the bottom m. The stems slide down on the perforated door m, and drop onto the ground, while anyT seed that may be left with the stems drop through the false bottom m onto the door m and empty into a box or measure attached to the end of the door m. By having the stem-chute M constructed thus I save whatever seed may pass with the stems beyond the seed-chute N.

By locating the hulling concave and cylindcr back of the thrashing-cylinder, and arranging the diierent parts of the machine as described and shown on the drawings, I obtain an arch back of the front wheels, which allows said front wheels to turn without interfering with the frame-work of the huller.

My machine, constructed as described, can be used forhulling either clover or rice, and for thrashing timothy.

Having thus fully described my improvements, what I claim, and desire to secure by Letters Patent, is-
